Specification of Letters Patent.

' Patented Jan. 14, 1908.

Application filed April 20. 1907. Serial No. 369382- To all whom it mayconcern:

Be it known that I, GEORGE W. WILSON, a citizen of the United States,residing at Cayuga, in the county of Vermilion and State of Indiana,have invented certain new and useful Improvements in Explosive-Engines,of which the following is a specification.

My invention relates more particularly to new and useful mechanism forregulating the speed of explosive engines now in common use, such asgas, gasolene or oil engines, and has for its object the production of amechanism of the character described whereby the speed of the engine maybe changed, regulated and controlled at will while running withouthaving to stop the engine as has been necessary heretofore and to thisend my invention consists in the peculiar construction, combination andarrangement of the several parts as will be more fully set forthhereinafter.

Referring to the accompanying drawings forming a part of thisspecification, in which like letters and numerals of reference indi catecorresponding parts throughout the several views; Figure 1 is anelevation of the main portion of an explosive engine showing myinvention applied to the same. Fig. 2 is a detail lan of my inventionentire. Fig. 3 is a detai view of the same obtained from the directionindicated by the arrow A, Fig. 2. Fig. 4 is an enlarged vertical sectionupon the line, m, n, Fig. 2. Fig. 5 is an enlarged detail of the tensionblock and thumb-wheel.

Before detailing the merits of my invention further it will be expedientto observe here that I have shown only the main portion of an explosiveengine provided with a well known governor for the reason that it isunnecessary to show and describe the other operating parts to disclosethe merits and operation of my improvement which is intended for useupon any well known form of ex losive engines in common use. Also it wi1 be readily seen that the operating parts of an explosive engine maywidely differ in form and operation without materially interfering withthe merits, operation and adoption of my invention in connection withthe same. By preference for an illustrative purpose I'have shown anexplosive engine of the well known vertical type in which the governoris mounted upon the gear-wheel instead of upon the "fly-wheel as ispracticed in the larger type.

A represents the main portion of an explosive engine, B the fly-wheel, Cthe base, and D the governor, all of which are of wellknownconstruction.

E and numerals represent the various parts of my improvement. Thegovernor comprises the weights D, the elbow-levers D and the sleeve DThe elbow-levers D are fulcrumed upon the gear-wheel at the points D andhave their inner ends set in an annular groove of the sleeve D and theirouter ends rigidly secured to the weights D.

The operation of the governor has been controlled heretofore by theprovision of an ordinary spiral spring secured by an adjustable link ora similar take-up device to and between the weights D and of such wellknown constructions that illustration and description is deemedunnecessary. The regulation of the operation of the governor by allknown means secured to and between the weights D for the purpose ofregulating and changing the speed of an explosive engine made itnecessary heretofore to stop the engine for allowing such means betweenthe weights D to be manipulated and adjusted to obtain the de siredoperation of the governor for producing the speed desired in the engine.The sleeve D which is freely mounted upon the gearshaft F has alongitudinal movement thereon which is produced by the operation of thegovernor for a well known purpose. The gear-wheel F which is rigidlysecured upon the gear-shaft F is driven by the gear-wheel F securelymounted upon the main driveshaft F The objectionable features to suchold and well known means of reguating' the opera.- tion of the governoris the loss of time occasioned by having to stop the engine for makingthe necessary manipulation and adjustment for producing the desiredspeed and the intervals of irregular explosions caused, more commonlytermed sputtering, in the run- A ning of the engine and it will now bemore readily apparent that the particular object of my invention is toavoid such old and well known means and to obviate these objections.

In the attainment of my object means heretofore secured to and betweenthe governor weights D for regulating the operation of the governor, arein my invention entirely discarded.

E represents the main frame of my invenhead E has an elongated. slottion, E the angle-lever, E the geared handwheel, E the threadedthumb-wheel, E the grooved tension block, E the downstandingtension-spring, E the tension pin, E the tension arm, and E the frictionroller which operates against the inner, annular collar of the governorsleeve D for affecting, as may be determined, its longitudinal movementupon the gear-shaft F for the well known purpose of properly timing theother necessary operating parts of an explosive engine. The main frame Eis fulcrumed to the main portion A of the engine by a suitablethrough-pin and nut E and is provided with a link-like head E adownstanding arm E and a downstanding slotted portion E. The link-like Eprovided with a cogged inner wall E which meshes with the cogged gear ofthe hand-wheel E The hand-wheel E has an instanding collar E providedwith-a cogged gear E at its inner end which inserts into the elongated.slot E and meshes with its cogged inner wall E and has a suitablecentral opening for the through-pin E of the main portion A upon whichit is rigidly secured by the nut E By manipulating the hand-wheel E? andthe nut E the main frame E may be tilted, set and secured as desired.The downstanding portion E has a long opening E for the reception of thegrooved tension block E The tension block E has a pair of parallelgrooves E for the reception of the side portions of the downstandingportion E of the main frame and an annular groove E for the reception ofthe forked end of the angle-lever E. The thumb-wheel E has a longthreaded stem E which passes through a suitable threaded opening in theblock E and has a look-nut E upon the threaded stem adjacent the tensionblock for rigidly securing it. The end of the stem E operates againstthe tension spring E and by manipulating the thumb-wheel and thelock-nut the stem E may be minutely adjusted and rigidly set against thetension spring E for procuring the most accurate adjustment. Theanglelever E is fulcrumed to the downstanding arm E at the point E andis provided with a finger-hold E an instanding pin E and aforked end E.The pin E inserts in suitable openings E in the main frame and theforked end E operates in the annular groove E of the tension block. Bymanipulating the finger-hold E the angle-lever E may be oscillated fromits position shown to any position desired over the openings E and thepin E set therein and by which operation the speed of the engine ischanged from the lowest to the highest or to any intermediate slpeeddesired while the engine is running.

he tension spring E at its upper end for the reception of the threadedprojection of the tension pin E and is rigidly secured thereon by thenut E has a suitable opening The tension pin E is freely mountedlin asuitable opening in the main portion A of the engine and has its innerthreaded projection inserted through a suitable opening in the lowerpart of the upstanding arm E which is rigidly secured thereon by the nutE The tension arm E at its upper end is provided with a rigid instandingpin E which passes through a suitable opening in the friction roller Ewhich is mounted freely thereon, adj acent the inner, annular collar ofthe governor sleeve D It will readily be seen that by manipulating thehand-wheel E and nut E and the thumb-wheel E and lock-nut E that theadjustment of the pressure of the friction roller E against the innerannular collar of the governor sleeve D may be attained and maintainedwith great exactness for the well known purpose of properly timing theoperations of the other necessary operating parts of an explosive enginefor establishing the limits of its maximum and minimum speed. It willfurther be apparent that by manipulating the angle-lever E by thefinger-hold E that five changes may be obtained in the speed of theengine which number I have found ample for all practical purposes. Theremay be obtained as many changes in the speed of the engine as there areopenings E provided in the main frame E for the pin E of theangle-lever. The correct objective to be sought in the adjustment of myinven tion is to obtain and maintain a tension or pressure through thefriction roller E against the longitudinal movement of the governorsleeve D upon the gear shaft F which will provide the lowest or minimumspeed upon which the engine can runwhen the anglelever E is positionedas shown in Fig. 1 and when the angle-lever E is oscillated to theopposite limit of its travel the highest or maximum speed is provided towhich the engine may be subjected.

The advantages of my invention are apparent to every one skilled in theart to which it pertains, such as economy of time and the saving offuel. It further obviates the objectionable sputtering and the necessityof friction clutches when used for various purposes.

Having thus fully described my invention and set forth the operation andadvantages thereof what I claim as new and desire to secure by LettersPatent is:
